Linux编程 - 使用C在MySQL中插入数据1. 代码编写#include <stdlib.h>
#include <stdio.h>
#include "mysql.h"int main(int argc, char *argv[])
{
MYSQL my_connection;
int res;
mysql_init(&my_connection);
if (mysql_real_connect(&my_connection, "localhost", "root", "mysql", "mysql", 0, NULL, 0))
{
printf("Connection success
");
res = mysql_query(&my_connection, "INSERT INTO children(fname, age) VALUES("david", 8)");
if (!res)
{
printf("Inserted %lu rows
", (unsigned long)mysql_affected_rows(&my_connection));
}
else
{
fprintf(stderr, "Insert error %d: %s
", mysql_errno(&my_connection),
mysql_error(&my_connection));
}
mysql_close(&my_connection);
}
else
{
fprintf(stderr, "Connection failed
");
if (mysql_errno(&my_connection))
{
fprintf(stderr, "Connection error %d: %s
",
mysql_errno(&my_connection), mysql_error(&my_connection));
}
}
return EXIT_SUCCESS;
